De Guzman was the last person seen with Arnaiz on the night the 19-year-old was killed in Caloocan after he allegedly shot it out with policemen who had accosted him for being in the wrong place at the wrong time.

The police had just received a report from a taxi driver that his last passenger held him up and Arnaiz just happened to be walking along the said route when police arrived to investigate.

According to his friends, Arnaiz had treated them to midnight snacks at a noodle house in the wee hours of August 18. After staying at the eatery for an hour, they hung out for several minutes at the Arnaiz’s sari-sari store in Cainta, Rizal.

One of Arnaiz’s friends said De Guzman arrived at the store just as they were about to call it a day and stayed with Arnaiz who didn’t want to go home just yet. It was the last time any of them would see Arnaiz and De Guzman alive.

Arnaiz’s body was found in a morgue in Caloocan 10 days later and De Guzman’s body turned up in a funeral home in Gapan, Nueve Ecija nine days after Arnaiz’s body was found.

De Guzman’s father believes his son was killed by Caloocan City policemen to prevent him from testifying on the killing of Arnaiz.
